This is somehow frowned upon by programmers (as selling yourself out) but as someone that took the plunge it is something I really suggest doing, if you are getting bored or just want to try new things.

You are presented with a new set of challenges and another point of view that, if anything, will make you appreciate more other roles and give you a better view of what delivering a product or a project entails, how different parts in a company interact, and how they are dependent on each other. More than moving "up" it really more like "sideways".

Also, if your company is receptive enough you could ask for an experience in another department, like sales or QA, or testing.

You can go back any time: a normal career spans decades, decisions are rarely definitive.
